Inorganic chemicals, dangerous reactions

Oxidation and reduction are fundamental processes in the synthesis of organic and inorganic compounds. Some oxidation and reduction reactions are difficult to control in macro-scale batch reactors and in such cases microflow reactors serve as powerful tools for accomplishing the reactions in a highly controlled manner. This is especially true for many oxidation reactions because of their exothermic nature. It should also be noted that the danger of unexpected explosions can be avoided by the use of microflow reactors because of the small volume and highly efficient heat transfer ability of microflow systems. This chapter provides an overview of oxidation and reduction reactions using chemical, electrochemical and biochemical methods in microflow reactors. 

SAFETY PROFILE A poison. Flammable by chemical reaction an oxidizer. Explosive reaction with hydrogen peroxide, chlorine + ethylene. Reacts violently with molten potassium, molten sodium, S, (H2S + BaO + air). Forms explosive mixtures with nonmetals [e.g., phosphorus (impact-sensitive), sulfur (friction-sensitive)]. Incompatible with alkali metals, reducing materials. Dangerous when heated to decomposition it emits highly toxic fumes of Hg. See also MERCURY COMPOUNDS, INORGANIC. 

DOT CLASSIFICATION 5.1 Label Oxidizer SAFETY PROFILE Dangerous fire hazard by spontaneous chemical reaction. It is a very powerful oxidizer. Fires of this material should be handled like sodium peroxide fires. Moderate explosion hazard hy spontaneous chemical reaction. Explodes on contact with water, forming H2O2 and KOH. Violent reactions with air, Sb, As, O2, K. Vigorous reaction on contact with reducing materials. On contact with acid or acid fumes, it can emit toxic fumes. Incompatible with carbon, diselenium dichloride, ethanol, hydrocarbons, metals. When heated to decomposition it emits toxic fumes of K2O. See also PEROXIDES, INORGANIC. 

MlNEHAL ACIDS are inorganic acids derived from chemical reactions. The discoveries of all three acids below are attributed to Jabir Ibn Hay (8th C.), as is Aqua Regia. NEVER add water to an acid, the reaction can generate considerable heat, and may boil and spit dangerously, ALWAYS add acids carefully to water. ...
